Doesn't this qualify as bashing? Granted, they are your opinions, but no one here has ever called him a messiah.
Closing Gitmo will get rid of the black eye that has been put on it since it came to light that the amount of torture that has taken place there. The timetable for complete withdrawl of combat troops in Iraq is mid-2010 (that was Bush's doing, not President Obama's), so bringing some of them back to have some time with their family before being redeployed to Afghanistan is not only a good idea but the law, especially since they should have never been in Iraq in the first place.
Don't you enjoy the idea of cleaner air, especially since there is scientific evidence that less pollution equates to a longer, healthier life? So you are putting a dollar amount on someone's life?
